As noted on the Bethesda Blog, the first patch for Fallout: New Vegas is now available automatically through Steam, where word is: "This update fixes quest and scripting issues." They say they are working on getting the console versions of Obsidian's RPG sequel patched as soon as possible, and also announce that the issue with PlayStation 3 digital preorder bonuses is now resolved.

And I get maybe 20fps with the water turned off, average settings and during the event early in the game, maybe 5.

Trying this 'hacked' dll file. Hope it works! It's far to early in the morning to test now, I'll post results when I get home early this afternoon.

Sounds like a potential Nvidia driver issue to me. We have nearly the same specs but I'm running a Radeon 5850 and I'm running on Ultra at very fluid and consistent framerates. The hacked D3D9 dll file has fixed most of the people on other forums who are having issues with framerates. There's a driver related performance issue with multisampling on some Nvidia cards and a CPU game bug related to facial emotions.

I gotta agree Verno....I am getting well above 30+ frames, as I notice no slow down or issues with the display....and I by no means have a killer rig.

Always remember to take your STEAM folder and My Docs out of your virus scanner program.
